Context Based Word Building

Hi Guys!
Well, the game is going interesting. However, as I had laid down the rules, the next word must be the last letter of the previous word - just as we play in a normal word building game. Otherwise, it looks like simply putting all words relevant to the "context".

Example: Railway Station is the Context

Engine -> start now with "e" again, as the last letter is "e" and context must be brought in to guess the word!

Good luck!
